White screen after window size change

I’m currently trying to make an options screen for my game. I’m trying to let the player change window size and if it’s full screen or not. My current code is

Game1.graphics.PreferredBackBufferHeight = (int)(Settings.Get(eSettings.ScreenHeight));
Game1.graphics.PreferredBackBufferWidth = (int)(Settings.Get(eSettings.ScreenWidth));

The window changes size but is blank and all white for some reason. This is using the windows version of Monogame 3.4. Anyone know what could be causing this?
